Bicycle recommendation needed

Separate bike question: best shifter style - twist shifter or trigger shifter or lever shifter?

I've had my bike for about 13 or 14 years, so it has old school lever shifter (handlebar mounted, not OLD old school crossbar mounted). When we were looking for a bike for my wife, I wanted to get trigger shifter, but those are typically found mostly on more expensive, specialty bikes.

I was against the grip-twist shifter, thinking it would not be very precise, but I've tried her bike and I was shocked at how well it worked.

Anyone else have any preference or other experiences?

Twist can work fine for recreational riding if you go with quality brands. The mid range Shimano and SRAM drivetrains offer decent performance with trigger, brifter, and twist shifters. Off brand and lowest end components will perform poorly and need more frequent adjustment regardless of form factor. Check MTBR for reviews of specific mtb/hybrid shifters.
